The steam fog refrigerating unit is used in a kind of thermal treatment; It comprises the nozzle cover of upper cover plate, side plate and bottom, and the two ends of said steam fog refrigerating unit are welded with baffle plate, it is characterized in that; Be fixed with equal water cavity in the nozzle cover of said upper cover plate, side plate, bottom, the inside cavity that baffle plate forms; Said equal water cavity below is provided with water jet, and said water jet inserts the opening on the said nozzle cover, and the slit of this water jet and this opening forms tuyere; On said cover plate, offer prosopyle and air inlet port, the top that water inlet pipe inserts said equal water cavity through this prosopyle, inlet pipe is fixed on this air inlet port.
The steam fog refrigerating unit is used in a kind of thermal treatment, it is characterized in that, said water jet comprises two nozzle plates, leaves the water spray slit in the middle of two nozzle plates.
The steam fog refrigerating unit is used in a kind of thermal treatment, it is characterized in that, is provided with the damping baffle that has through hole above in said equal water cavity.
The steam fog refrigerating unit is used in a kind of thermal treatment, it is characterized in that, said equal water cavity is fixed on the inboard of said side plate through fixed block.
The steam fog refrigerating unit is used in a kind of thermal treatment; It is characterized in that said thermal treatment is with the long 2.8m～4.3m of steam fog refrigerating unit, slit width 2～5mm sprays water; Jet slit width 1.5～3mm is angled with the water spray slit, and is that the axis forms symmetric arrangement with the water spray slit.
Material of the present invention is stainless steel, and welding portion adopts argon-are welding technology, and postwelding carries out stress relief annealing in 200～500 ℃ of scopes, finally guarantees whole refrigerating unit straight, indeformable under high-temperature work environment.Corresponding packing technique is all adopted in the bolt connection portion, guarantees that the gentle passage separately of water does not disturb mutually.
Beneficial effect of the present invention:
1, cooling range of the present invention can realize the even cooling to strip more than or equal to the width of strip to be cooled.
2, the present invention is processed into aquaporin and the air passageways that does not communicate through welding technique, thereby has the cooling of the water and air mixing back formation aerosol realization of certain pressure to the thin plate band in the exit.
3, the present invention realizes the homogeneity of current through steel plate being processed the equally distributed through hole of two rows, thereby guarantees the homogeneity of the aerosol that forms.
